<note>
June 3 2025 

I'm working on this project again....

First try... [[..:allstar:gm4slv_allstar_2025|]]

And then more, much more... [[..:allstar:allstar_expands|]]

 * DTMF Commands
  * Please send * 7 3 to ensure all links are disconnected before making any new links

^Command	^DTMF Sequence^
|Disconect from Node xxxx	|  * 1 xxxx  |

^  Name  ^* 5 Macro shortcut to...	^  DTMF Sequence  ^  Node No.  ^
|  Hubnet  |Disconnect from Hubnet	|  * 5 1 1  |  41223  |
|  Hubnet  |Connect RX Only to Hubnet	|  * 5 2 1  |  41223  |
|  Hubnet  |Connect Transceive to Hubnet	|  * 5 3 1  |  41223  |



===== Courtesy Tones =====


Can give information about the node status.

After a local Transmission on the "input" frequency the reponse will be one of:

  * Morse Letter **I** (di-dit) = node is not connected to any other nodes
  * Morse Letter **R** (di-dah-dit) = node is connected in "Monitor/RX only" mode to one or more nodes
  * Morse Letter **K** (dah-di-dah) = node is connected in "Transceive" mode to one or more nodes

There are other tones, e.g. when a station on a linked node unkeys there's a low-pitched "bloop"

When a local RF station sends a command there's a "bip bip" (not to be confused with the Morse letter I)


===== Echolink =====

AllStar nodes can also connect to [[https://www.echolink.org/logins.jsp|Echolink]]

The node is occasionally connected to Echolink as ''GM4SLV-L ''


<del>
(**UPDATE** --- //John Pumford-Green 24/04/23 14:47// )

I have disabled the Echolink connection by editing ''/etc/asterisk/modules.conf'' to change the channel driver for Echolink to ''noload'' ->

</del>

To turn Echolink **ON** or **OFF** edit ''/etc/asterisk/modules.conf''

** OFF **

<code conf>
noload => chan_echolink.so ;
</code>

** ON **

<code conf>
load => chan_echolink.so ;
</code>

an Asterisk reload is necessary:

<code bash>
gm4slv@mb7aze:/etc/asterisk$ sudo astres.sh
Restarting Asterisk
systemctl restart asterisk.service
</code>
